Vlier SSS64 Threaded Spring Plunger 3/4-10 Stainless Steel

Product Description

The VLIER SSS64 is a threaded spring plunger designed for indexing, positioning, and light-duty retention applications in industrial and mechanical assemblies. It features a 3/4-10 thread with a 1-3/4 inch thread length and a stainless steel body and nose for corrosion resistance in demanding environments. The spring delivers an initial end force of 6.7 pounds and a final end force of 37.3 pounds, providing reliable, repeatable engagement force. The plunger nose diameter ranges from 0.373 to 0.374 inches with a 5/16 inch projection. Machinists, tool and die technicians, and maintenance mechanics install this type of component in fixtures, jigs, and machine slides where controlled detent or stop action is required.

The SSS64 is suited for use in manufacturing fixtures, assembly tooling, machine tool slides, and automation equipment where a spring-loaded detent point is needed. The stainless steel construction makes it appropriate for wet, washdown, or mildly corrosive service conditions. It installs into a tapped through-hole or blind hole and can be torqued to the desired preload position without a locking element. Both light-force indexing and moderate-force retention setups are within its operating range given the 6.7 to 37.3 pound end force spread.

Key Features

• 3/4-10 thread size with 1-3/4 inch thread length for secure installation depth
• Initial end force of 6.7 pounds and final end force of 37.3 pounds for a wide engagement range
• Stainless steel body and nose for corrosion resistance in harsh or washdown environments
• Plunger nose diameter of 0.373 to 0.374 inches with 5/16 inch projection
• No locking element - position is set by thread engagement depth alone
• Standard plunger length type for drop-in replacement into existing tapped bores

Compatibility

Designed as an OEM-style or aftermarket replacement threaded spring plunger for industrial fixtures, jigs, machine tool slides, and automation assemblies requiring a 3/4-10 tapped bore and stainless steel construction.

Installation Notes

Installation requires a properly tapped 3/4-10 through-hole or blind hole in the mating component. De-energize or lock out any machine or assembly before installing or adjusting spring plungers in moving or powered mechanisms. Thread engagement depth controls preload and functional projection, so verify plunger projection after installation before returning the assembly to service. Use appropriate thread-locking compound if vibration loosening is a concern in the application.
